Abstract

The main objective of the paper is to develop a GIS-based method for delineating spatial clusters. Major tasks are: (i) to devise a sustainable algorithm with reference to various methods developed in the fields of geographic boundary analysis and cluster detection; (ii) to develop a GIS-based program to implement the algorithm. The main results are as follows. First, it is recognized that the AMOEBA technique utilizing LISA is the best candidate. Second, a modified version of the AMOEBA technique is proposed and implemented in a GIS environment. Third, the validity and usefulness of the modified AMOEBA algorithm is assured by its applications to test and real data sets.

이 연구의 주된 목적은 공간 클러스터의 범역을 설정하는 GIS-기반 방법론을 개발하는 것이다. 주요 과제는 지리적 경계 분석과 LISA-기반 클러스터 탐지에 대한 기존 방법론을 비교 검토함으로써 진일보한 방법론을 고안하고, 그것을 실행하는 GIS-기반 프로그램을 개발하는 것이다. 주요 연구 결과는 다음과 같다. 첫째, 기존 방법론을 검토한 결과, LISA를 이용한 AMOEBA 기법이 가장 타당한 것으로 판단되었다. 둘째, 수정 AMOEBA 기법의 알고리즘을 확립했으며 실행 소프트웨어를 상용 GIS 프로그램의 확장 기능형태로 개발하였다. 셋째, 수정 AMOEBA 기법을 실험 데이터와 실 데이터에 적용한 결과 제안된 기법의 유용성이 확인되었다.
